Specification of Letters Patent.

Patented Feb. 2.), 1916.

Application filed lune 16, 1915. Serial No. 34,467.

T 0 all whom it may concern:

Be it known that I, RAFAEL M. Amman, a citizen of the Republic of Cuba, residing at Habana, Island of Cuba, have invented certain new and useful Improvements in Penholders, of which the following is a specification, reference being had to the accompanying drawings.

My present invention relates to new and useful improvements in pen holders and as its principal object aims to provide a device of this character which is so constructed that the pen points used in the holder may,-

after becoming corroded with ink or otherwise rendered unfit for use. be easily and quickly ejected from the holder, without requiring that the operator directly grasp the pen point itself. 7

A further and more specific object of the invention is to provide a pen holder of this character which includes as its essential elements of construction, a stem or staff, a fixed sleeve, which is secured upon the terminal of the stem or staff, a second sleeve which is 'slidable upon the fixed sleeve and is adapted to clamp the inner end of the pen point upon the end of the staff, and spring members which are disposed between the fixed sleeve and movable sleeve for limiting the movement of this latter member toward the end of the staff, to permit the sleeve to be moved away from the end of the staff when the pen point is to be removed.

Another and general obiect'of the invention is to provide a pen holder which possesses the above characteristics but is, at the same time, relatively simple in construction so that it may be cheaply manufactured.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appended hereto and forms part of this application.

Withreference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals desigpen holding device, showing the sleeves applied to a staff or stem, which is shown in full lines; Fig. 2 is a composite view showing the fixed sleeve applied to the staff and the movable sleeve removed from the fixed sleeve; and Fig. 3 is a section on the line 3-3, of Fig. 1.

As embodied in the accompanying drawings, the pen holder of the present invention preferably includes a stem or staff 10 of conventional design; a fixed sleeve 11, which is mounted upon the end of the staff and proects some distance therebeyond; a slidable sleeve 12, which is mounted upon the fixed sleeve; stop springs 13, which are disposed between the fixed and movable sleeves, for limiting the outward movement of this latter member; and a fixed annular stop 14 which is formed at the inner end of the fixed sleeve for limiting the inward movement of the movable sleeve.

The fixed sleeve 11 is preferably formed from a single blank of sheet metal and is, as shown in Fig. 1 tubular in shape. The inner end'of the sleeve is open and is slipped over the staff The stop member, heretofore designated by the numeral 14 is formed as shown in Fig. 1 on the inner end of this sleeve and is adapted to limit the inward sliding movement of the movable sleeve, in a manner which will hereinafter become ap parent. The-outer end of the fixed sleeve proiects a considerable distance beyond the terminal of the staff and is preferably provided with slits or kerfs 15 which release resilient gripping tongues 16.

At diametrically opposite points, the fixed sleeve is, as best shown in detail'in Fig. 2 provided with pairs of parallel longitudinal slits 17 and transverse slits 18. A slit 18 is formed at oneend of each of the spring tongues 19 defined by the parallel slits to re lease these members 19 from the sleeve. As is shown in Fig. l the two spring tongues are directed outwardly and are terminally bent to form the inwardly extending lugs 20.

The sleeve 12 is provided with an internal annular groove 21, the one wall of which indicated at 22, extends at right angles to the longitudinal axis of the sleeve and the other wall 23 of which extends at an acute angle thereto. The angle which the wall 23 bears to the wall 22 corresponds to the angle of the tongues 21 to the lugs 20.

Referring now to Fig. 1 it will be readily signed and related to the movable sleeve observed that when the movable sleeve is set upon the fixed sleeve, the spring tongues seat within grooves and bear against theinclined wall 23 thereof, while the lugs of the springs are adapted to seat against the wall 22 of the groove. Thus the spring tongues" been applied thereto. At the same time, it will-beo served that the; movable sleeve may beslid inwardly, without hindrance, since the spring tongues will be moved'in wardly into the sleeve 11 by the inclined wall of the movable sleeve. VVhena pen point is to be inserted in my pen holder, the bowed portion of the pen is inserted between thegripping'jaws-1'6 and the outer end of the sleeve 12 in the same manner as though the penpointwere applied to an ordinary pen holder. When thetpen is to be'removed from the pen holder. the sleeve 12 is moved inwardly on the sleeve 11.- The spring tongues 13 move inwardly in the manner previously explained to permit such inward movement of the sleeve 12. The inward movement of the sleeve 12' will obviously uncover the outer endof-thefixed sleeve 11 and as ayresult the bowed portion-of the pen point willbe uncovered and the pen, therefore, allowed to drop from the pen holder.

Ino'w desire to particularly-explain that while springs of the type shown in the accompanying drawings are preferably employed, I do not'wish to limit myself to this specific construction, since it is obvious that diflerent' types of springsmay be substi tuted for' those shown. without departing. in any way from the spirit ofthe invention. It isvonly essential that the springs be so clethat they will limit the outward'movement of this member on the j movable sleeve, but

will permit the -movable' sleeve to be readily? withdrawn from engagement with the pen point, so that this member may be removed from the pen holder. In this connection, it will be obvious that the springs may be carried' by the movable sleeve and arranged for 'eng'a geinnt with the fixed sleeve, instead ofbeing oppositely arranged, as in the accompanying drawings.

It willalso be apparent-thatthe spring.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents; 7

tongues may be formed as separate elements and'rivet'ed, sold'ered,'or otherwise suitably secured" to the member 11.

. By' forming-the sleeve 12 with an annular groove it is possible to rotate the sleeve 12' therebetween {may be overcome and the sleeve. 12' readily disengaged from the'pen 6. Where the sleeve 1-2 is only reciprocat able; the ink oftenIdries and prevents the withdrawal of the sleeve without considerable force-being; exerted.

In reduction to practice, it has been found that the form .of this invention illustrated in the drawings,- and referred to in the above description as the preferred embodimentis the most efficient and practic'alyyet realizing that the conditions concurrent with the'adoption of this device will neces sarily vary, it is desirable to emphasize the fact that various minor changes in the details of construction, proportion and arrangement of parts may be resorted to,

when required, without; sacrificing anv of length than the fixed sleeve and adapted to clamp the butt of a pen point against the outer end'of the pen, said movable portion being provided with an internal annulargroove, said stop tongues being engageable t in the groove for limiting the outward movement of the'movable sleeve and being depressedby' the movable sleeve when the same is moving away from the forward end" of the fix'ecl sleeve,ithe annular groove per -mittingl rotary movement of the movable" sleeve uponnthe stoptongues and upon the fixed 'sleeve.-
